lldiv(3C)

NAME

     div, ldiv, lldiv - compute the quotient and remainder

SYNOPSIS

     #include <stdlib.h>

     div_t div(int numer, int denom);

     ldiv_t ldiv(long int numer, long int denom);

     lldiv_t lldiv(long long numer, long long denom);

DESCRIPTION

     The div() function computes the quotient  and  remainder  of
     the  division  of  the  numerator  numer  by the denominator
     denom. It provides a well-defined semantics for  the  signed
     integral  division  and  remainder  operations,  unlike  the
     implementation-defined semantics of the built-in operations.
     The  sign of the resulting quotient is that of the algebraic
     quotient, and if the division is inexact, the  magnitude  of
     the  resulting quotient is the largest integer less than the
     magnitude of the algebraic quotient. If the result cannot be
     represented,  the behavior is undefined; otherwise, quotient
     * denom + remainder will equal numer.

     The ldiv() and  lldiv()  functions  are  similar  to  div(),
     except  that  the  arguments and the members of the returned
     structure are  different.  The  ldiv()  function  returns  a
     structure of type ldiv_t and has type long int.  The lldiv()
     function returns a structure of type lldiv_t  and  has  type
     long long.

RETURN VALUES

     The div()  function  returns  a  structure  of  type  div_t,
     comprising both the quotient and remainder:

     int   quot;   /*quotient*/
     int   rem;    /*remainder*/

     The ldiv() function returns a structure of type  ldiv_t  and
     lldiv() returns a structure of type lldiv_t, comprising both
     the  quotient and remainder:

     long int   quot;   /*quotient*/
     long int   rem;    /*remainder*/
